NOTE to ensure the maximum spread width is obtained large hard dense slug pellet must be used.
Ensure the two spread patterns meet and just overlap in the centre, and reach out each side of centre to give the
required total width.
Some smaller, lighter and less dense pellets may not reach the full width especially in breezy conditions, and
with many pellets the pattern may be thinner towards the outer edges. Ensure conditions are good and the discs
are a minimum of 2 meters above the ground or crop canopy for 36m work. Ensure the spread width and
pattern is adequate for your requirements before going to work.
The Fan Jet Duo comprises of two separate machines, and each machine, left hand and right hand are
calibrated as an individual machines when setting the application rate (Kgs/Ha) and spread width,
the combined overall rate and spread width of both machines should equal the total required.
You will have to perform a catch and weigh test to establish the flow rate of product, and will need a suitable
container to collect the product being metered and an accurate set of scales to weigh kilograms and grams, and
a timer.
We recommend using the supplied Calibration Hopper with the spinning disc turned OFF, and control the feed
motor with the Remote Calibrate Switch
To establish the correct flow rate of pellets for your bout width, forward speed and application rate
use the below formula;
Method
Use the following formula to establish the flow rate – this is a 1 minute catch test universal for all machines,
products, widths and speeds.
Application rate (kgs/ha) x forward speed (kph) x spread width (metres) = Flow rate in kgs per min
600
Example 1.
The required application rate is 25 kilograms per hectare. The target forward speed is 10 kilometres per hour.
The bout width is 6 metres wide.
25 kgs/ha x 10 kph x 6 metres = 2.5kgs per minute flow rate
600
Example 2.
The required application rate is 5.5 kilograms per hectare. The target forward speed is 12 kilometres per hour.
The bout width is 4.25 metres wide.
5.5 kgs/ha x 12 kph x 4.25 metres = 467 grams per minute flow rate
600
The flow rate required is the combined output of both machines.
NOTE Machines are supplied from factory with two feed fitted in each feed block assembly
This combination suits most 24m to 36m slug pellet applications
If lower rates required then 1 feed roller per feed block assembly can be fitted
For higher rates or if say traveling at high speeds such as UTV work the extra feed rollers
supplied can be fitted to give 3 feed rollers in each
